Let's Replace That Taco Circulator Pump

Hot water heating system repair is something that many homeowners will find intimidating.

For some, with less then adequate mechanical ability, that may be a good thing.
For others, who have a hands on attitude towards their home repairs, a small amount of information can and will give you the capability to pull this repair off yourself.

If you're not quite sure which category above you fit in, then you can ask yourself a few simple questions to figure that out.

1) Can you Identify most, if not all of the components on your boiler and within the heating system?

If not you may be interested in this e-book to begin with "Understanding Hot Water Heating Systems" By yours truly. That's available from Amazon for the Kindle, I know, shameless plug but it will explain the conventional hot water heating system from start to finish.

2) Can you positively shut off the electrical power to the system? 

Normally a hot water heating system will have an emergency switch located at the boiler. It's always a good idea to shut off the power at the electrical panel and then test the circuit to be positive there's no power. This is an inexpensive electrical tester for $19.15 that will prove the power is off.

3) Do you own a set of standard open end wrenches and a four way screw driver?

If not I can solve that as well, here's the open end wrench set for $24.99, and here's the four way screwdriver for $3.99

Once you can answer yes to all three questions above then you're ready to tackle replacing your Taco circulator pump, potentially saving yourself hundreds of dollars on heating repair bills.

How To Change a Cartridge on a Taco Circulator Pump

Taco Circulator Cartridge Replacement Procedure

Hot water heating systems commonly use a sealed circulator pump for each zone of hydronic heating. Some systems have one pump, running one zone or loop. Some systems have several zones and some have many. There really is no limit to how many pumps can be installed, it all depends on how many areas that need to be controlled individually. 

Each zone will be controlled by it's own thermostat. Some system designs will incorporate zone valves that open and close when that zone's respective thermostat calls for heat or shuts off.

What all of these system designs have in common is their Taco circulator pumps. These pumps have a great reputation and amazing longevity. Like anything else mechanical they also break down eventually. 

The procedure for repairing a modern Taco cartridge circulator pump is very simple, most people can accomplish this repair themselves with common hand tools.

Taco circulator pumps use a small cylinder shaped electric motor that has a built in impeller which inserts into the body of the pump.

Replacing the cartridge is normally all that's required when a pump fails. This can be accomplished by removing four small retaining bolts that hold the body of the pump together.

If you'd like to learn more about this job and possibly attempt the repair yourself then we highly recommend this e-book;

How To Eliminate Noise In A Hot Water Baseboard Heating System

Typically noise within a baseboard system can come from two different sources. The first and most common way that noise will become evident within your heating system is an introduction of unwanted air within the piping. This will make a noise like a river flowing, or a babbling brook outside the window.

Split That Heating Into Multiple Zones and Save!!

Hot water heating systems come in many shapes and sizes.  The simple ones may be just one zone, with one pump and some baseboard.

Complicated hydronic systems may have as many zones as there are rooms in the home.  They may also add a zone to produce domestic hot water.

There are many benefits to splitting up your heating system into zones, such as the comfort level of your family.  You'll also save money on fuel costs.

Another great benefit of splitting a hot water heating system, is the increased longevity you'll get from the boiler.

Other mechanical components such as circulator pumps and zone valves, will also last a lot longer because they're only working to heat a fraction of the system rather then the whole house.

This type of a system works much harder to heat the whole residence at once, than it will to heat each zone every once in a while to maintain the set-points.

Splitting a hot water heating system into separate zones will take adding a thermostat for the added zone or zones, and configuring the feed and return on the boiler to except the new zone, or zones.

I've written several extensive articles just for this subject.  You can check them out over on

Simple open/closed zone valves can be used to split an existing system.  Honeywell has always offered the most dependable of these valves at a reasonable price.

Easy to install and boasting a motor that can be replaced in minutes, this valve will offer decades of service in a hydronic application.

Problems With Your Taco Pump

Circulator pumps are the workhorse's of the hot water heating system. They quietly send that hot water to far away rooms. They automatically come on and off with only a slight nudge from a thermostat.
Circulator pumps run for years without a single blip, and then they just quit. They'll burn up quick once they go and a replacement motor will be in order.
Replacing a motor on a cartridge circulator pump is a pretty simple job, providing there are shut-off/isolation valves handily installed on both sides of the pump.
If valves to isolate the pump where never installed then you'll have to drain down the system make the repair and re-purge everything when you're done.
All of that takes time and another quicker way is to pull a vacuum on the system and make the repair without draining the system.  
When leaks occur in circulator flanges, air can be drawn into the piping and cause problems over time. This air will sound like a river running through your home. Getting the air out can be quite a chore if you're not familiar with the procedure. 
Purging a hot water heating system is an art you can master. Quieting down the air will also create savings in fuel consumption because the system will run much more efficiently.

Taco Circulator Pumps Repair Or Replace?

Sometimes a new pump makes
more sense then a costly repair.

Leaking Hot Water Heating Systems

Even a properly designed and installed
hot water heating system can develop leaks.
Fixing them right away
can increase the lifespan of the system.
If you have a leaking hot water heating system, your robbing yourself of the longevity your boiler and all of the components can offer.

Hot water heating systems are supposed to be sealed systems. This means that once they are pressurized and purged of all the air, the water in the system stays in the system and no more need be added unless there is a leak.

When leaks occur in a hot water heating system, there is an automatic feed valve that replaces the water that leaks out with new water from your city supply or your well.

This new water also contains minerals and oxidants that will rot out the non-ferrous parts of a hot water heating system. This means anything not made of copper or brass is susceptible to decay from the added water.

Included is the boiler and any cast iron or black iron fittings, pump bodies, fittings and pipes. All of these system components are attacked when new water is added.
Normally the substances in the water that can harm the system are distilled quickly and settle to the bottom of the boiler where they will do no harm. Adding water constantly will defeat this distillation process and rot out the system quickly.

I've seen boilers begin leaking within six months of installation because leaks were never fixed.

To get the most out of your hot water heating system; be sure to fix any leaks immediately.
